Definitions
- a support member which is separated from such a substrate is from the figures 8 and 9 of EP 0 671 705 A2 known.
- the local support element is for installation in a Chip card provided, which is both contact over a Number of contact surfaces as well as contactless via an antenna coil, for example via transformer coupling, can be operated.
- Carrier elements for chip cards serve the mechanical support of the semiconductor chip and also have the for contacting of the chip required contact surfaces. They will both used in purely contact smart card, so that Access to the semiconductor chip only via the contact surface is possible, as well as in so-called combi cards, in which additionally a contactless access by means of conductor loops in the card and / or on the carrier element or the chip is possible.
- the conductor loops are used for this purpose Coil terminals of the semiconductor chip connected.
- support elements are usually not individually, but on a long tape or a large scale benefit made of a non-conductive material in large quantities.
- This - hereinafter referred to as substrate - Band or the benefits are first by example Punching recesses structured and then one-sided with laminated a copper foil, which then, for example is patterned by etching, so that the contact surfaces for the individual support elements are formed. All senior Structures are initially still elekrisch through narrow lines conductive interconnected to a galvanic O-surface finishing to carry out.
- the semiconductor chips are located opposite to the contact surfaces Side of the substrate attached and by means of bonding wires through the recesses electrically with the contact surfaces connected.
- the support element of EP 0 671 705 A2 has the coil terminals of the semiconductor chip through recesses in the substrate through with contact surfaces on the chip opposite Side of the substrate connected.
- the ends of a to be connected Antenna coil also with these contact surfaces by recesses provided in the substrate for this purpose through connected to two of these contact surfaces.
- the Contact surfaces thus serve as connecting elements between Coil and semiconductor chip. But this has the disadvantage that the Coil terminals of the semiconductor chip from the contact surface side accessible, even after the carrier elements are isolated.
- the document EP 0 581 284 A2 describes a contactless chip card with integrated within the chip card integrated Circuit units described. On the outside of the chip card There are test pads with the circuit units are connected. During the test operation are accessible to these test pads. Then they will covered by a non-conductive material.
- test pads are with vias with the Contact surfaces connected on the top, so that after assembly the chip's function via the test pads can be checked without turning the module.
- the object of the present invention is therefore to provide a carrier element, which is produced on a substrate, wherein the coil terminals of a semiconductor chip to be mounted accessible from the contact surface side, as long as the support element is still in the band or use and after the isolation of this accessibility is prevented.
- the task becomes by a substrate according to claim 1, which is delimited against EP 0 671 705 A2, solved.
- the recesses are covered with conductive surfaces, those with the conductor structures with which the semiconductor chip or chips and the coil (s) are connected.
- the test tips can then easily through the recesses be placed on the surface.
- Another training provides, the recesses on the Contact surface side of the substrate with a conductive surface cover over the vias through the recesses through with the conductor structures on the chip side of the substrate are connected.
- the vias can in this case fill the recesses completely or only theirs Cover walls.
- FIG. 1 shows a detail of a band 1 on which four carrier elements are formed in pairs. It is, however possible, a larger number than two support elements to arrange next to each other on the band.
- the band consists of a non-conductive substrate 2, wherein as material, for example fiberglass reinforced epoxy resin can.
- the substrate 2 has perforations 3 along both edges on, the further transport by means of the perforations 3 engaging driver, for example in the assembly of the band with semiconductor chips or the function test, serve.
- the outer contour of a carrier element is indicated by a dashed line Line 4 indicated.
- the ready equipped carrier elements are punched out of the band 1 along this line 4 or otherwise cut out.
- the non-conductive substrate 2 was coated with a metal foil, preferably a copper foil, laminated.
- a metal foil preferably a copper foil, laminated.
- the metal foil was structured so that contact surfaces 5 within the carrier element outer contour line 4 as well further contact surfaces 6, outside the outer contour line 4 of the support element are incurred.
- the contact surfaces 5, 6 are on narrow lines 7 with the outer contour lines 4 running lines 8 and thus all together connected. This electrical short circuit is necessary because the Contact surfaces 5, 6 are galvanically surface-finished.
- FIG. 2 shows the other side of the substrate 2 on which the (Not shown) semiconductor chip is mounted. These too Side is created by Metallfolienkaschieren and etching Ladder structures 9, 10, 11, 14, 15 provided.
- the substrate was initially on one side with a metal foil laminated and then with recesses 12, 13, the provided for example by punching provided.
- recesses 12, 13, the provided for example by punching provided To the subsequent etching of the conductor structures 9, 10, 14, 15 must the recesses 12 are covered so that the recesses 12 remain around metallizations 11, which for contacting used the coil terminals of a semiconductor chip can be.
- the metallizations 11 each form closed conductive rings around the recesses 12 around. to Prevention of potentially occurring eddy current losses but also interruptions can be provided.
- first recesses 12 within the outer contour line 4 and serve the electrical Connection of the semiconductor chip with those on the other side of the substrate 2 lying contact surfaces 5 by means of bonding wires.
- Second recesses 13 are designed as plated-through holes, the other contact surfaces 6 via lines 14th connect to coil terminal pads 10.
- the substrate 4 is relatively flexible. In a chip card would a semiconductor chip mounted thereon considerable bending loads be exposed. Larger chips would even break. For this reason, a reinforcing frame (not shown) becomes on the chip side of the carrier element with an insulating adhesive glued.
- the reinforcing frame is preferably made of metal, but it can also be made of a different material be.
- the metallization ring 9 under the reinforcing frame allowed not be closed, otherwise the coil ends shorted would. However, this creates additional parasitic Capacity between the open ends of the metallization ring 9 and the one or more lines 15. To these capacities As low as possible, the gap is in the metallization under the frame on the one hand so large as possible, but on the other hand only so big that the potting compound can not run out of the frame.
- the semiconductor chip can now be over the contact surfaces. 5 as in normal operation in a smart card test.
- the contactless Operation can be in accordance with the invention of the Contact surface side over the other contact surfaces 6, via the vias 13 and the lines 14 with the coil terminal contact surfaces 10 are connected, test.
- the lines 14 severed and the vias 13 and the others Contact surfaces 6 not components of a support element, so that an access from the contact side of the support element the coil terminals of the semiconductor chip no longer possible is.
- the lines 14 is used in a in a smart card Carrier element access to the coil terminals only still possible via a connected antenna coil.
- the other contact surfaces 6 are not necessarily necessary. It would be enough, the recesses with conductive Material to fill. However, that would be the test of tips area to be contacted significantly smaller.
